l Leum Patent. No. 66,398, dared .my 2, 1861 IMPROVBD BEDSTEAD.

ono-

TO ALL WHOM IT MAY CON CERN:

Be it known that I, ANDREW ROTHWELL, of Washington, in the county of Washington, und District of Columbia, have invented n new and useful Improvementin Bedsteads; and I do hereby declare that the following is a, full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure 1 is n side view, with one rail and port of the end pieces removed.

Figure-shows a'modication of my invention.

This invention consists in an improved arrangement or disposition of bedstead-slat, the object and advantage being to produce a'depressed or curved surface adapted to the form of the humnnbody.

This bedsteed, whilst it is greatly promotive ofthe comfortable repose of all persons, is peculiurlyndnpted to contribute to the ease end rest of aged persons and invalide, -who are compelled to pass much of their time in n recumbent position. The depression should commence with the third or fourth'slat fromthe head of the bed, dependent upon the number of sluts and the spaces separating them; Three or four slats should be set below the level of the others, forming a regular curved line. The lowest point of depression may be from two to tliree inches, ns the manufacturer may find most desir-allele. With this arrangement a comfortable bed may' be made, with much les's thickness'thau is necessary withthe level position ofthe slats as ,commonly used.

It will be readily perceived that the application of my improvement in the manufacture of bedsteads will cost no more than as at present constructed, whilethe alteration of those already in use may be made at a. trilling'expense. l

In order that others skilled in the nrt to which my inventionnppertnns may be enabled to fully understand. null use the same, I will proceed to describe it in detail.

In the drawings, A B C D represent mortises,w hich are cnt deeper than the others, in the rofl of the bedstead, or-a. strip secured thereto, inwhich the ends of the slats (shown in red) rest. The bases of two of these mortises, A D, :we inclined, as shown in the drnwing, While B C are level; or, the bases of all the depressed mortisos muy be inclined so that the lowest point `\vi ll be between the two lower sla-2s, forming e regulr curve, of about twofeet in extent, as shown in g. 2.

Having thus described my invention, the following is what claim as new therein, and desire to se re by Letters Potent: I claim so disposing the slats of' bedsteads as to produce o curved depression therein, adapted to the form ofthe human body, substantially as described and represented.
